Passenger elevators are vertical transportation systems designed to move people between different floors of a building. They are commonly found in high-rise buildings, shopping malls, and hotels, providing a convenient way to travel without using stairs. These elevators are equipped with safety features, such as emergency brakes and alarms, ensuring a secure ride for passengers. Modern passenger elevators come in various sizes and designs, accommodating different capacities and aesthetics. They often include user-friendly controls, such as buttons for each floor and sometimes even touchless options. With advancements in technology, smart elevators can optimize travel routes, improving efficiency and reducing wait times for users.
